The most common brands in Harare are Phocos, Mecer, Synapse, Must, 5-Star, Rebel as well as Growatt. These inverters cost around $130 to $200 per KVA. For example, the table below shows the prices of these inverters at Taqon Electrico. [pdf]
The voltage of an inverter is not always 220V after conversion. While many inverters are designed to output a standard voltage of 220V AC, this can vary based on the inverter type and design.Inverters typically convert lower DC voltages (like 12V, 24V, or 48V) to AC voltages, often aiming for 220V, but the actual output can depend on the inverter's specifications and settings2.The output voltage can also be adjusted based on the components used in the inverter circuit2.Additionally, the voltage can fluctuate slightly around the nominal value (e.g., 220V, 230V, or 240V) depending on the load and other factors3.Thus, while 220V is a common target, it is not guaranteed to be the exact output in all cases.
